Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, a kind of embodiment of optics module of the present utility model is elaborated.The optics module of the present embodiment comprises LED light source 1 and lens 2, and the light of described LED light source 1 is through described lens 2 outgoing.Described optics module also comprises light-blocking member 3, and described light-blocking member 3 blocks the light at incidence surface 21 edges of lens 2 described in described LED light source 1 directive at least partly.Described light-blocking member 3 is provided with the shading surface 31 around described LED light source 1, and described shading surface 31 is blocked the light at incidence surface 21 edges of lens 2 described in described LED light source 1 directive at least partly.In the present embodiment, described light-blocking member 3 comprises conical wall 37, and described shading surface 31 is the inner surface of described conical wall 37.Because the edge of the incidence surface 21 of described lens 2 can only receive the light that the part light-emitting area of described LED light source 1 is sent, therefore the hot spot that the light at the edge of the described incidence surface 21 of process forms diminishes, thereby the marginal definition of the whole hot spot of described optics module is improved.In the present embodiment, described light-blocking member 3 comprises tabular part and is formed at the downward sunk part of the central area of tabular part, and the internal face of sunk part is described shading surface 31 downwards.As shown in Figure 2, in the present embodiment, straight line a is the straight line through the marginal point E of the incidence surface of described lens 2 and the top edge of described shading surface 31; Straight line b is the straight line through the marginal point D of the incidence surface of described lens 2 and the top edge of described shading surface 31.Straight line a, straight line b are A and B with the intersection point of the light-emitting area of described LED light source 1 respectively.The light of the circle region c taking straight line AB as diameter of described LED light source 1 light-emitting area cannot be irradiated to the edge of the incidence surface of described lens 2, be that described shading surface 31 is blocked the light in circle region c, make this part light cannot be irradiated to the edge of the incidence surface 21 of described lens 2.Because the edge of the incidence surface 21 of described lens 2 can only receive the light that the part light-emitting area of described LED light source 1 is sent, therefore the hot spot that the light at the edge of the described incidence surface 21 of process forms diminishes, thereby the marginal definition of the whole hot spot of described optics module is improved.Described shading surface 31 is E with the angle of the optical axis of described LED light source 1, and as shown in Figure 3, straight line d is the straight line parallel with the optical axis of described LED light source 1, and the angle E between straight line d and shading surface 31 is the angle of shading surface 31 and described LED light source 1.In the time that the angle of angle E increases, the definition of hot spot is along with increase, but will cause the reduction of optics module light efficiency, and in the time of 30 ° of angle E <, the light efficiency of optics module is higher, but the edge of hot spot is clear not enough; And in the time of 60 ° of E >, the marginal definition of hot spot is higher, but the light efficiency of optics module is lower, all can not meet the demands well.In the time of 30 °≤E≤60 °, the edge of the hot spot of optics module is comparatively clear, and the light efficiency of optics module is also higher, between hot spot marginal definition and light efficiency, has reached good balance.In the present embodiment, E=45 °.It needs to be noted, in Fig. 2, the vertical center line of the light-emitting area of described LED light source 1 is the optical axis of described LED light source 1.Described light-blocking member 3 is made up of the opaque material of insulation, for example made of plastic.Described light-blocking member 3 is provided with the support portion 32 for supporting described lens 2.In the present embodiment, described support portion 32 is extended and is formed to the direction away from described LED light source 1 from the edge of described light-blocking member 3, is the vertical wall of annular.By support portion 22 is set, can conveniently control the distance between LED light source 1 and lens 2.Described light-blocking member 3 also comprises connecting portion 39, and described connecting portion 39 is tabular, and described connecting portion 39 connects described conical wall 37 and described support portion 32.Described lens 2 are biconvex lens, and the incidence surface 21 of described lens 2 and exiting surface 22 are all convex surfaces.Described LED light source 1 is COB light source.Incidence surface 21 one end of described lens 2 are also provided with the L-shaped ring support of cross section 29, and described ring support 29 can be made of plastics, and described ring support 29 can be connected with described lens 2 by bonding mode.Described lens 2 are arranged on described support portion 32 by ring support 29, and described ring support 29 can be connected with described support portion 32 by clamping or the mode being threaded.
As the simple deformation of above-described embodiment, described lens 2 can be also planoconvex spotlight, and the incidence surface of described lens 2 is planes, and its exiting surface is convex surface.
As the simple deformation of above-described embodiment, described angle E can be also 31 °, 32 °, 33 °, 34 °, 35 °, 36 °, 37 °, 38 °, 39 °, 40 °, 41 °, 42 °, 43 °, 44 °, 46 °, 47 °, 48 °, 49 °, 50 °, 51 °, 52 °, 53 °, 54 °, 55 °, 56 °, 57 °, 58 °, 59 ° or 60 °.
